Omnitetrachordal MODMOS scale
12L+2s
14 tones (6+2+6)
Injera
MODMOS. Imperfect (P<0); best for L/s >= 1.5
P
= -8.6918120831
Q
= 16.8836241662 (4/3 = 5L+0.5s)
L = 85.71 to 100.00 cents (99.02 cents @ Q)
s = 0.00 to 85.71 cents (5.87 cents @ Q)
9/8 = 2L (171.43 to 200.00 cents)
4/3 = 5L+s (500.00 to 514.28 cents)
MOS generator = L (85.7 to 100.0 cents)
MOS
period
= 1/2 octave (600.00 cents)
notable EDOs: 26, 38, 40, 50
